Title: Improvements in yarn or analogous winding or like machines
IPC: B65H54/24
Filed: 1926-04-29
Abstract: 268,161. Abbott, E. J. April 29, 1926. Winding-machines; spindle-driving apparatus.-In a yarn-winding machine for winding headless cheeses comprised of overlapped layers of reversed spiral windings, the winding and corresponding unwinding yarn masses are travelled in succession continuously along a predetermined path during winding, the winding being temporarily discontinued at one point in the path to enable fresh unwinding yarn masses to be placed in the machine and pieced by an operative stationed at that point. The path travelled by the cheeses is preferably endless or circulatory. Each cheese 93, Fig. 1, is wound on a spindle supported in an extension 90 of the carrier 10 and rests upon a longitudinal roller 70 and is driven thereby at a constant surface speed. The carriers 10 are supported on rails 4, 5 having curved ends 4<a>, 5<a>, and are moved round the machine by driving lugs connected to links 22 on an endless chain 20 driven by sprocket wheels 25, 26, Fig. 2. The bracket 30, 31 supporting the wheel 25 and its shaft 27 is adjustable to take up slack in the chain 20, while the wheel 26 is driven from the shaft 42 through a belt 45 and gearing 37., 38, Fig. 3. The driving rolls 70 are also driven from the shaft 42 through gearing 60, 61, 64, 65. Each traverse guide 99 is formed in the upper end of the vertical arm of a bellcrank lever 101, 102 pivoted at 103 on the carrier 10 and having an antifriction roller 104 engaging in a channel 105, which latter is rocked by arms 107 on a shaft 59 actuated by an arm 110 driven by the cam track 57. The pulley 54 having the cam track 57 formed therein is driven by a belt 53 from the shaft 42. The supply bobbins B are supported on the carriers 10 and the machine is designed so that the supply bobbins are exhausted when the carriers have made a complete circuit. On reaching the shield 80 the cheeses 93 cease to be driven bv the rolls 70, and the traverse of the guide 99 diminishes, ceasing entirely at the end of the machine. The exhausted bobbin is therefore doffed, a fresh supply bobbin substituted and winding recommences when the carrier leaves the shield 80.

Title: Improvements in pulse-code modulation signal transmitters
IPC: H04J3/06
Filed: 1951-05-15
Abstract: 698,706. Multiplex pulse code signalling. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 15, 1951 [May 17, 1950], No. 11351/51. Class 40 (v). In a pulse code modulation transmitter in which a synchronizing pulse is transmitted once per signal cycle and the intelligence signal comprises a variation in the relative presence and absence of pulses in the channel, all the pulses transmitted being similar to one another and coinciding with pulses taken from a train of equidistant pulses, control pulses are transmitted in a signal channel by suppressing all pulses therein. The embodiment described is a time division multiplex transmitter with one synchronizing channel and nine signal channels, the modulators being of the type in which the coding device is fed from a difference producer supplied with the modulating signal and the demodulated output of the coder. An alarm signal is produced in any signal channel, and the channel cut out, if signal pulses occur continuously therein or are absent continuously. The master oscillator 10 controls a pulse generator 11, which sends synchronizing pulses to the output conductor 23 through the delay network 46<SP>1</SP>. The pulses are also fed to the delay line distributer 13, tappings 14 ... 22 on which are connected to channel circuits A1 .. , A9 respectively. The circuit of channel A3 is shown in detail. The modulating signal and D.C. control pulses are applied to terminals 28, 29, the signal being applied to the difference producer 32 through transformer 30. The mixer 34 passes pulses from tapping 16 to the pulse widener 35 only when the output from circuit 32 is positive. The widened pulses are integrated in circuit 38 to provide the demodulated signal which is applied to the difference producer 32. They are also fed to the potential divider 39 and thence through condenser 41 and resistance 42 to the control grid of pentode 43. This valve is normally cut off but passes pulses through condenser 48 to the output conductor 23 during the coincidence of a control grid pulse and a pulse fed to the suppressor grid from tapping 16 through delay network 46. The D.C. control pulses at terminals 28, 29, operate a relay 50 to disconnect the pulse source 16 at contact 51 or 51<SP>1</SP>. The cut-off bias for valve 43 is developed across condenser 44, by diode 53 fed with the widened pulses from circuit 35 through condenser 52. Condenser 44 is also connected to the junction of condenser 41 and resistance 42 so that if circuit 35 supplies pulses continuously or fails to supply pulses for a considerable time the bias voltage disappears and the increase in screen current operates monitoring relay 56. Contact 58 thereupon removes the screen polarizing voltage to disable the valve and closes a holding circuit, which includes an alarm lamp 60. Specifications 662,611, 684,318, 691,824 and 698,708 are referred to.

Abstract: 270,316. Aktiebolaget Separator, (Assignees of Hulbert, J. L.). April 30, 1926, [Convention date]. Cow-milkers. - To facilitate the fixing in its shell a of the liner b of a milking-machine teat cup an expansible device g is inserted into an anchored end c of the liner and is expanded by the introduction thereinto of an expander k whereby a locking is effected between the device and the liner and then by movement of the shell relatively to the device, the liner is stretched to such a position that its free end can be secured to the other end of the shell. As shown, the expansible device comprises bent wire fingers secured to a base e which also carries a pivoted wing i. When the device is first inserted into the liner this wing is put in its inner position so that it limits the entry of the device, as shown in Fig. 2, and then after the expander has been forced into place the wing is swung outwards to permit the pressing down of the shell, and finally it is swung inwards again, Fig. 4, to lock the device in position until the upper end of the liner has been turned down and fixed bv the nozzle d and ring d<1>.

Title: Process for the production of hydroxyaryl-alkyl thioethers
Filed: 1958-04-10
Abstract: Hydroxyaryl alkyl thioethers are prepared by reacting an aromatic hydroxy compound having at least one free p-position or one free o-position with an alkyl sulphenyl halide.  The alkyl sulphenyl halide may be prepared in situ by the action of a sulphuryl halide or an an alkyl thiol or a dialkyl disulphide. The reaction may be carried out at temperatures in the range -20 DEG  to 50 DEG C. in the presence or absence of inert diluents such as toluene, chloroform, chlorobenzene, xylenes or tetrachlorethane and condensation agents such as hydrochloric acid, benzene sulphonic acid, zinc chloride or boron trifluoride.  Since a hydrogen halide is evolved small quantities of water may be added to the reaction mixture.  In the examples methyl sulphenyl chloride is reacted with phenol to give 4-hydroxy-1-methylmercapto benzene, m-cresol to give 3-hydroxy-6-methylmercapto toluene, m-chlorophenol to give 3-hydroxy-6-methylmercapto-chlorobenzene; sulphuryl chloride and di-methyl disulphide are reacted with phenol, o-cresol to give 2-hydroxy-5-methylmercapto toluene, p-cresol to give 4-hydroxy-5-methyl-mercapto toluene, m-cresol, m-chlorophenol, 4-chloro-2-hydroxy toluene to give 2-hydroxy-4-chloro-5-methylmercapto toluene, 6-chloro-3-hydroxy toluene to give 3-hydroxy-4-methyl-mercapto - 6 - chlorotoluene, phenol in the presence of ferric chloride and phenol in the presence of water; sulphuryl chloride and methyl mercaptan are reacted with phenol; sulphuryl chloride and di-n-butyl disulphide are reacted with phenol to give 4-hydroxy-n-butylmercapto benzene and using diethyl di-sulphide 4-hydroxy-ethylmercapto benzene is obtained; sulphuryl chloride and dimethyl di-sulphide are reacted with b -naphthol to give 1-methylmercapto - 2 - hydroxy-naphthalene; methyl sulphuryl chloride and dimethyl di-sulphide are reacted with resorcinol to give 2,4-dihydroxy-1-methylmercapto-benzene.
